Usage

RecaptchaFieldType

When doing functional testing it is not possible to use the real Google Recaptcha API therefor there is a SimpleThings\FormExtraBundle\FunctionalTest\Recaptcha which always returns true.

It can be used by overwriting the DependencyInjection parameter in app/config/config_test.yml

The formextra_recaptcha form type takes a widget_options setting which is encoded as json and set to the configuration javascript variable Recaptcha needs. This allows you to change the theme for the widget or roll your own. For more information about what is possible check here http://code.google.com/apis/recaptcha/docs/customization.html.

PlainType

Sometimes it is needed to show the value of a field without having it be an input box. This is where PlainType comes in handy. It will render a simple p tags with the fields value and also prevent that field from being bound if the form is tampered with.

FileSetType

FileSetType allows you to incrementally add more files to a collection of files by extending the FileType. It renders an unordered list of all the previously uploaded base filenames.

Instead of returning the previously added file you return an array of all file names from the fields getter method and in the setter method you append the newly uploaded file to the collection:

Using the builder to create a field for this type would then look like:

There are optional parameters 'delete_route' and 'delete_id' which are then used with twigs path method to generate a route with parameters "id" and "file", to delete the listed file. If the information passed is not enough you should overwrite the twig template with your own logic to implement deleting.

TranslationDomainExtension

This field extension provides the forward compatibility for the support of translation domains added in Symfony 2.1. So activating it is useful only when using Symfony 2.0 (activating it in Symfony 2.1 will add useless overhead)

To use it, you need to activate it and to register the form theme using the translation domain.

You can now provide the translation domain used for labels and choice options when building the form:

HelpExtension

This field extension provides help message option.

To use it, you need to activate it and to register the form theme using the translation domain.

You can also load the help extension form theme into your own form theme.

You can now provide the help message for field when building the form:

HtmlEntitiesTransformer

Converts html code into entites. Also extends htmlentities function to auto guess the used charset if mbstring extension is availible.

StripTagsTransformer

Provides easy tag stripping capabilities for your forms to reduce xss attacks. You note it is not the best solution.
